ABSTRACT

OBJECTIVE: The Stress Management and Resilience Training (SMART) program is an evidence-based intervention designed to build resilience in physicians in clinical practice. The objective of the current study was to assess the impact of the SMART program on academic physicians’ levels of resilience, subjective happiness, stress, and anxiety, and specifically during the implementation of a new hospital-wide Health Information System (HIS).

METHODS: A total of 40 physicians in a tertiary care academic hospital were randomized (allocation ratio 1:1) to either the SMART intervention or the control condition. The SMART intervention consisted of one mandatory two-hour in-person workshop and an optional 24-week online program, designed to support the materials delivered in the workshop. Outcome measures were assessed using validated scales administered online at baseline and at 3-months and 6-months follow-up.

RESULTS: After adjusting for baseline levels of each outcome, no statistically significant intervention effect was observed for resilience, subjective happiness, stress or anxiety at 3-months or 6-months follow-up. However, physicians in the intervention group demonstrated improvements in resilience, stress and anxiety at follow-up that were within the range of clinically relevant differences.

CONCLUSIONS: The findings of this exploratory study provide modest support that the SMART intervention may be beneficial for proactively addressing physician wellness during the implementation of a new HIS and that larger randomized trials are warranted.

ABSTRACT

Access to low-frequency acoustic information in cochlear implant patients leads to better speech understanding in noise. Electrocochleography (ECochG) can provide real-time feedback about the health of the cochlea during the insertion process with the potential to reduce insertion trauma. We describe our experiences of using this technique. Data from 47 adult subjects with measurable residual hearing and an Advanced Bionics (Valencia, CA) SlimJ (46) or MidScala (1) electrode array were analyzed. ECochGs were recorded intraoperatively via the implant. The surgeon adjusted the course of the electrode insertion based on drops in the ECochG. The final array position was assessed using postoperative imaging and pure tone thresholds were measured before and after surgery. Three different patterns of ECochG response amplitude were observed: Growth, Fluctuating and Total Loss. Subjects in the growth group showed the smallest postoperative hearing loss. However, the group with fluctuating amplitudes showed no meaningful correlation between the ECochG responses and the postoperative hearing loss, indicating that amplitude alone is insufficient for detecting damage. Considering the phase of the signal additionally to the amplitude and reclassifying the data by both the phase and amplitude of the response into three groups Type I-Type III produced statistically significant correlations between postoperative hearing loss and the grouping based on amplitude and phase respectively. We showed significantly better hearing preservation for Type I (no drop in amplitude) and Type II (drop with a concurrent phase shift), while Type III (drop without concurrent phase shift) had more surgery induced hearing loss. ECochG potentials measured through the implant could provide valuable feedback during the electrode insertion. Both the amplitude and phase of the ECochG response are important to consider. More data needs to be evaluated to better understand the impact of the different signal components to design an automated system to alert the surgeon ahead of damaging the cochlea.

ABSTRACT

A variety of oxytocin regimens are used for labor induction and augmentation. Considering the increasing rates of labor induction, it is important to assess the most optimal oxytocin regimen without compromising maternal and fetal safety. The aim of this study was to compare delivery outcomes of low-dose and high-dose oxytocin induction protocols. This retrospective cohort study of 487 women comparing low-dose oxytocin protocol (n = 280) and high-dose oxytocin protocol (n = 207) in labor induction following cervical ripening by balloon catheter was performed in Helsinki University Hospital after implementation of a new oxytocin induction protocol. The study included two six-month cohorts from 2016 and 2019. Women with vital singleton pregnancies ≥37 gestational weeks, cephalic presentation, and intact amniotic membranes were included. The primary outcome was the rate of vaginal delivery. The secondary outcomes were the rates of maternal and neonatal infections, postpartum hemorrhage, umbilical artery blood pH-value, admission to neonatal intensive care, and induction-to-delivery interval. Statistical analyses were performed by using IBM SPSS Statistics for Windows (Armonk, NY, USA). The rate of vaginal delivery was higher [69.9% (n = 144) vs. 47.9% (n = 134); p<0.004] and the rates of maternal and neonatal infection were lower during the new high-dose oxytocin protocol [maternal infections 13.6% (n = 28) vs. 22.1% (n = 62); p = 0.02 and neonatal infection 2.9% (n = 6) vs. 14.6% (n = 41); p<0.001, respectively]. The rates of post-partum hemorrhage, umbilical artery blood pH-value <7.05 or neonatal intensive care admissions did not differ between the cohorts. The median induction-to-delivery interval was shorter in the new protocol [32.0 h (IQR 18.5-42.7) vs. 37.9 h (IQR 27.8-52.8); p<0.001]. In conclusion, implementation of the new continuous high-dose oxytocin protocol resulted in higher rate of vaginal delivery and lower rate of maternal and neonatal infections. Our experience supports the use of high-dose continuous oxytocin induction regimen with a practice of stopping oxytocin once active labor is achieved, and a 15-18-hour maximum duration for oxytocin induction in the latent phase of labor following cervical ripening with a balloon catheter.

ABSTRACT

BACKGROUND: Taller adult height is associated with lower risks of ischemic heart disease in mendelian randomization (MR) studies, but little is known about the causal relevance of height for different subtypes of ischemic stroke. The present study examined the causal relevance of height for different subtypes of ischemic stroke.

METHODS AND FINDINGS: Height-associated genetic variants (up to 2,337) from previous genome-wide association studies (GWASs) were used to construct genetic instruments in different ancestral populations. Two-sample MR approaches were used to examine the associations of genetically determined height with ischemic stroke and its subtypes (cardioembolic stroke, large-artery stroke, and small-vessel stroke) in multiple ancestries (the MEGASTROKE consortium, which included genome-wide studies of stroke and stroke subtypes: 60,341 ischemic stroke cases) supported by additional cases in individuals of white British ancestry (UK Biobank [UKB]: 4,055 cases) and Chinese ancestry (China Kadoorie Biobank [CKB]: 10,297 cases). The associations of genetically determined height with established cardiovascular and other risk factors were examined in 336,750 participants from UKB and 58,277 participants from CKB. In MEGASTROKE, genetically determined height was associated with a 4% lower risk (odds ratio [OR] 0.96; 95% confidence interval [CI] 0.94, 0.99; p = 0.007) of ischemic stroke per 1 standard deviation (SD) taller height, but this masked a much stronger positive association of height with cardioembolic stroke (13% higher risk, OR 1.13 [95% CI 1.07, 1.19], p < 0.001) and stronger inverse associations with large-artery stroke (11% lower risk, OR 0.89 [0.84, 0.95], p < 0.001) and small-vessel stroke (13% lower risk, OR 0.87 [0.83, 0.92], p < 0.001). The findings in both UKB and CKB were directionally concordant with those observed in MEGASTROKE, but did not reach statistical significance: For presumed cardioembolic stroke, the ORs were 1.08 (95% CI 0.86, 1.35; p = 0.53) in UKB and 1.20 (0.77, 1.85; p = 0.43) in CKB; for other subtypes of ischemic stroke in UKB, the OR was 0.97 (95% CI 0.90, 1.05; p = 0.49); and for other nonlacunar stroke and lacunar stroke in CKB, the ORs were 0.89 (0.80, 1.00; p = 0.06) and 0.99 (0.88, 1.12; p = 0.85), respectively. In addition, genetically determined height was also positively associated with atrial fibrillation (available only in UKB), and with lean body mass and lung function, and inversely associated with low-density lipoprotein (LDL) cholesterol in both British and Chinese ancestries. Limitations of this study include potential bias from assortative mating or pleiotropic effects of genetic variants and incomplete generalizability of genetic instruments to different populations.

CONCLUSIONS: The findings provide support for a causal association of taller adult height with higher risk of cardioembolic stroke and lower risk of other ischemic stroke subtypes in diverse ancestries. Further research is needed to understand the shared biological and physical pathways underlying the associations between height and stroke risks, which could identify potential targets for treatments to prevent stroke.

ABSTRACT

Lymphoma is accompanied by the impairment of multiple immune functions. Cytokines play an important role in a variety of immune-related functions and affect the tumor microenvironment. However, the exact regulatory mechanisms between them remain unclear. This study aimed to explore the cytokines expression and function in Hodgkin’s lymphoma (HL), diffuse large B-cell lymphoma (DLBCL), and mantle cell lymphoma (MCL). We performed a transcriptome integration analysis of 14 lymphoma datasets including 240 Hodgkin’s lymphoma, 891 diffuse large B-cell lymphoma, 216 mantle cell lymphoma, and 64 health samples. The results showed that multiple immune functions and signal pathway damage were shared by all three types of lymphoma, and these functions were related to cytokines. Furthermore, through co-expression network and functional interaction network analysis, we identified CXCL14 as a key regulator and it affects cell chemotaxis and migration functions. The functional experiment showed that CXCL14 knockdown inhibited cell migration in MCL cell lines. This study suggested that high expression of CXCL14 may aggravate MCL via promoting cell migration. Our findings provide novel insights into the biology of this disease and would be helpful for the pathogenesis study and drug discovery of lymphomas.

ABSTRACT

Mass vaccination is critical to control the pandemic of coronavirus disease 2019 (COVID-19). Fear of adverse events (AEs) after COVID-19 vaccination is a main factor associated with vaccination hesitancy. We aimed to analyze AEs in healthcare workers (HCWs) vaccinated with COVID-19 vaccines (Aikewei or CoronaVac) composed of inactivated virus. We used a structured self-administered questionnaire to conduct two surveys on COVID-19 vaccination among HCWs in perinatal medicine and obstetrics/gynecology from April 5 to April 21, 2021. In total, 1392 HCWs who had received at least one vaccine dose were included. Of them, 1264 (90.8%) were females and 1047 (75.2%) received two doses. The overall incidence of any AEs after the first and second dose was 38.2% (532/1392) and 31.0% (325/1047) respectively (χ2 = 13.506, P = .0002). Female and HCWs aged 18-30 y were more likely to report AEs. The most common AEs were local reaction, accounting for 48.1% and 67.4% of all AEs after the first and second dose respectively. The systemic AEs were mainly neurological (9.8% and 4.8% after the first and second injection respectively) and flu-like symptoms (6.3% and 3.2%). Overall, most of AEs were mild, only 5.1% (after the first dose) and 2.8% (after the second dose) of individuals with AEs received symptomatic treatment or sick leaves, and none of them required hospitalization. Our data added more evidence that inactivated COVID-19 vaccines are highly safe. The data are valuable to overcome vaccine hesitancy associated with concerns about the safety of COVID-19 vaccines.

ABSTRACT

INTRODUCTION: This study compared outcomes of soft tissue reconstruction using biodegradable temporizing matrix (BTM) and collagen-chondroitin silicone (CCS) skin substitutes.

OBJECTIVE: In this study, the authors compared wound healing rates and complication rates between BTM and CCS.

MATERIALS AND METHODS: This retrospective study reviewed outcomes for adult patients who underwent soft tissue reconstruction with either BTM or CCS skin substitutes between 2015 and 2020. Demographics, wound characteristics, surgical details, and complications were recorded.

RESULTS: Ninety-seven patients were included, of whom 51 (52.6%) were treated with BTM graft and 46 (47.4%) with CCS bilayer graft. The mean patient age was 48.2 years (range, 18-93 years). Wound etiologies included burn, trauma, iatrogenic, compartment syndrome, skin cancer, and osteomyelitis. The median template size was 147 cm2 and 100 cm2 for BTM and CCS, respectively (P =.337). Skin grafts were applied to 39 patients (84.8%) treated with CCS compared with 28 (54.9%) treated with BTM (P =.006); the remaining wounds healing secondarily. The template-related and skin graft-related complications of infection, dehiscence, and hematoma or seroma were comparable between groups. The rate of skin graft failure was significantly higher in the CCS cohort (n = 9 [23.1%]) compared with the BTM group (n = 1 [3.6%]) (P =.006). More secondary procedures were required after CCS placement (mean ± standard deviation, 1.9 ± 1.8; range, 0-9) than after BTM (mean, 1.0 ± 0.9; range 0-4) (P =.002). There was no statistical significance in the frequency of definitive closure between BTM and CCS (n = 31 [60.8%] vs n = 28 [60.9%], respectively; P =.655).

CONCLUSIONS: Compared with CCS, BTM had comparable closure and complication rates and required fewer secondary procedures and/or subsequent skin grafting.

ABSTRACT

PURPOSE: To compare non-absorbable and absorbable sutures for medial rectus advancement in consecutive exotropia.

METHODS: In a pilot randomized clinical trial, 40 subjects with consecutive exotropia >15 PD that underwent unilateral medial rectus advancement with or without resection were randomly assigned to two groups: using non-absorbable (polyester) suture in the non-absorbable group and absorbable (vicryl) suture in the absorbable group. The success rate was defined as the final postoperative angle of deviation <10 PD.

RESULTS: Thirty-three patients (18 in the non-absorbable and 15 in the absorbable group) had completed the study. At last follow-up, the distance deviation improved from 29.2 ± 15.5 to 7.6 ± 7.9 in the non-absorbable group and from 25.9 ± 8.4 to 8.1 ± 10.7 in the absorbable group. The near deviation improved from 31.4 ± 15.9 to 7.2 ± 8.0 in the non-absorbable and from 29.0 ± 7.6 to 6.8 ± 11.9 in the absorbable group. The amount of the final correction of the distance and near deviation was not statistically different between the groups (P = .80 and P = .99, respectively). At the final examination, the exoshifts for distance and near were not statistically different between 2 groups (p = .61 and 0.54, respectively). At the final examination, the success was obtained in 12 patients (66.7%) and 8 patients (53.3%) in the non-absorbable and absorbable group, respectively (p = .73).

CONCLUSION: In our study, there was no statistical difference in success rate or exoshift between non-absorbable and absorbable sutures. So, considering local inflammation induced by non-absorbable sutures in some cases, the absorbable sutures can be an appropriate option for the treatment of consecutive exotropia.

ABSTRACT

Two service members were diagnosed with PTSD due to military trauma exposure. One presented with the classical manifestation; the other presented with the dissociative subtype. A statistical map revealed anterior localization of insula connectivity in the classical PTSD patient and posterior localization in the dissociative PTSD patient. These differences suggest that dissociative PTSD may be identified, understood, and treated as a disorder related to increased posterior insula connectivity. This double case study provides preliminary evidence for a concrete neuroanatomical discrepancy between insula function in classical and dissociative PTSD that may help explain the emergence of different coping strategies.

ABSTRACT

The study was conducted to determine the death anxiety experienced by heart patients and the affecting factors in the COVID-19 pandemic. The study was conducted with 148 patients hospitalized in the cardiology clinic of a university hospital between April and August 2021 in the southeast in Turkey. The data were collected with the personal information form, death anxiety scale, coronavirus anxiety scale and Covid-19 fear scale developed by the researchers. Data analysis was performed by using IBM SPSS Statistics 25. Descriptive statistics were used in the analysis of the data. Correlation and regression analysis were performed to determine the relationship between scales. The mean age of the patients was 64.99+15.56 years and 56.1% were male. 57.4% of them were hospitalized with a diagnosis of coronary artery disease. During the pandemic, it was determined that 74.3% of the patients followed social distance, 71.6% wore masks, 58.8% used disinfectants. The patients had moderate death anxiety, low coronavirus anxiety, and high covid 19 fear. A positive linear correlation was found between anxiety and fear scale and death anxiety total and sub-dimensions. As a result, the fear of COVID-19 may increase the fear of death in individuals with heart disease. Patients who are worried about being infected with Covid 19 during the pandemic process have more fear of death.
